⚖️ How is the Opportunity Score calculated?
Starting from a base of 50/100, the score is adjusted by:
- LPA approval rate (±15) — Above 82% national average lifts the score; below penalises it.
- Tilted balance (+15) — If the LPA can't demonstrate a 5-year housing land supply, NPPF 11(d) applies.
- Supporting policies (up to +10) — +2 per identified supporting policy in the development plan / NPPF.
- Risk policies (down to −20) — −8 per "high risk" policy (e.g. Green Belt, Conservation Area, listed building setting), −3 per medium risk.
- Positive live reforms (up to +12) — +4 per recent reform that explicitly favours your proposal type.
Result is clamped to 0-100. Bands: 0-39 challenging · 40-59 moderate · 60-74 favourable · 75-100 strong opportunity.
